The array[]+={} syntax for Arma 3 was introduced as an attempt to add unique weapons (or magazines) to a unit without the tedium of duplicate-typing all the basic items.

It originally had a text-only interpreter making it quite impossible to generate config.bin's versus config.cpp's. Later, Binarize was modified to create new token code for this syntax. This token code is broken as it bears no relationship to any other tokenised output. It 'works' simply because its data format can be ignored.

It is not present in any form in any of the official addons accompanying Arma 3.

Usage

class A
{
	array[] = { any, thing };
};

class B : A
{
	array += { more, Bstuff };
};

class C : A // inherits from A, -not- B
{
	array += { other, Cstuff };
};
Only direct inheritance of an explicitly-stated array works. The following cases do not work:
class A { array[] = { any, thing }; }
class B : A {};
class C : B // inherits from B which inherits from A (without changes)
{
	array[]+ = { wont, work }; // result: array[] = { wont, work };
};
class A { array[] = { any, thing }; };
class B : A { array[] += { more, stuff }; };
class C : B // inherits from B which inherits from A (with += changes)
{
	array[] += { wont, work }; // result: array[] = { wont, work };
};
